Object Parser Error?

function objectParser(str)
    local obj = game.Players.LocalPlayer.PlayerGui
    local s, e = str:find'.-%.'
    if not s then
        return game[str:match'.+']
    else
        local object = str:match'.-%.'
        obj = game[object:sub(1, #object - 1)]
        print(object, str, e)
        str = str:sub(e)
        print(str)
        local leftovers = str
        for word in str:gmatch'%..-%.' do
            local s, e = str:find(word)
            leftovers = str:sub(e + 1)
            print(word)
            obj = obj[word:sub(2, #word-1)] -- Line 17
            print(leftovers)
        end
        return obj[leftovers]
    end

Lane is a StringValue and I'm using an ObjectParser to make it functional. I'm doing this so that the script can figure out which note is prioritized in a Dance Dance Revolution GUI game. Lane's value is a full name of an object. For example Lane.Value=Players.Player.PlayerGui.Game.Board.Lanes.LeftLane.16

Don't Know what's wrong. Please help.
